RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application Ser. No. 61/441,824, filed Feb. 11, 2011, the disclosure of which is hereby incorporated in its entirety herein by reference.

FIELD OF THE INVENTION

The present invention relates to novel 1-(1-Oxo-1,2,3,4-tetrahydroisoquinolin-7-yl)urea derivatives, processes for preparing them, pharmaceutical compositions containing them and their use as pharmaceuticals as modulators of the N-formyl peptide receptor like-1 (FPRL-1) receptor. The invention relates specifically to the use of these compounds and their pharmaceutical compositions to treat disorders associated with the N-formyl peptide receptor like-1 (FPRL-1) receptor modulation.

BACKGROUND OF THE INVENTION

The N-formyl peptide receptor like-1 (FPRL-1) receptor is a G protein-coupled receptor that is expressed on inflammatory cells such as monocytes and neutrophils, as well as T cells and has been shown to play a critical role in leukocyte trafficking during inflammation and human pathology. FPRL-1 is an exceptionally promiscuous receptor that responds to a large array of exogenous and endogenous ligands, including Serum amyloid A (SAA), chemokine variant sCKβ8-1, the neuroprotective peptide humanin, anti-inflammatory eicosanoid lipoxin A4 (LXA4) and glucocotricoid-modulated protein annexin A1. FPRL-1 transduces anti-inflammatory effects of LXA4 in many systems, but it also can mediate the pro-inflammatory signaling cascade of peptides such as SAA. The ability of the receptor to mediate two opposite effects is proposed to be a result of different receptor domains used by different agonists. Parmentier, Marc et al. Cytokine & Growth Factor Reviews 17 (2006) 501-519.

Activation of FPRL-1 by lipoxin A4 or its analogs and by Annexin I protein has been shown to result in anti-inflammatory activity by promoting active resolution of inflammation which involves inhibition of polymorphonuclear neutrophils (PMNs) and eosinophils migration and also stimulate monocyte migration enabling clearance of apoptotic cells from the site of inflammation in a nonphlogistic manner. In addition, FPRL-1 has been shown to inhibit NK cytotoxicity and promote activation of T cells which further contributes to down regulation of tissue damaging inflammatory signals. FPRL-1/LXA4 interaction has been shown to be beneficial in experimental models of ischemia reperfusion, angiogenesis, dermal inflammation, chemotherapy-induced alopecia, ocular inflammation such as endotoxin-induced uveitis, corneal wound healing, re-epithelialization etc. FPRL-1 thus represents an important novel pro-resolutionary molecular target for the development of new therapeutic agents in diseases with excessive inflammatory responses.

SUMMARY OF THE INVENTION

This suspension may be formulated according to known methods using suitable dispersing or wetting agents and suspending agents. The sterile injectable preparation may also be a sterile injectable solution or suspension in a non-toxic parenterally-acceptable diluent or solvent, for example, as a solution in 1,3-butanediol. Sterile, fixed oils are conventionally employed as a solvent or suspending medium. For this purpose any bland fixed oil may be employed including synthetic mono- or diglycerides, fatty acids (including oleic acid), naturally occurring vegetable oils like sesame oil, coconut oil, peanut oil, cottonseed oil, etc., or synthetic fatty vehicles like ethyl oleate or the like. Buffers, preservatives, antioxidants, and the like can be incorporated as required.

The compounds of the invention may also be administered in the form of suppositories for rectal administration of the drug. These compositions may be prepared by mixing the invention compounds with a suitable non-irritating excipient, such as cocoa butter, synthetic glyceride esters of polyethylene glycols, which are solid at ordinary temperatures, but liquefy and/or dissolve in the rectal cavity to release the drug.

Since individual subjects may present a wide variation in severity of symptoms and each drug has its unique therapeutic characteristics, the precise mode of administration and dosage employed for each subject is left to the discretion of the practitioner.

The compounds and pharmaceutical compositions described herein are useful as medicaments in mammals, including humans, for treatment of diseases and/or alleviations of conditions which are responsive to treatment by agonists or functional antagonists of the N-formyl peptide receptor like-1 (FPRL-1) receptor. Thus, in further embodiments of the invention, there are provided methods for treating a disorder associated with modulation of the N-formyl peptide receptor like-1 (FPRL-1) receptor. Such methods can be performed, for example, by administering to a subject in need thereof a pharmaceutical composition containing a therapeutically effective amount of at least one invention compound. As used herein, the term “therapeutically effective amount” means the amount of the pharmaceutical composition that will elicit the biological or medical response of a subject in need thereof that is being sought by the researcher, veterinarian, medical doctor or other clinician. In some embodiments, the subject in need thereof is a mammal. In some embodiments, the mammal is human.

The present invention concerns also processes for preparing the compounds of Formula I. The compounds of formula I according to the invention can be prepared analogously to conventional methods as understood by the person skilled in the art of synthetic organic chemistry. Synthetic Scheme 1 set forth below, illustrates how the compounds according to the invention can be made.

Compounds within the scope of the invention may be prepared as depicted in Scheme 1. In general, an aldehyde, such as 4-cyanobenzaldehyde, and an amine, such as N¹-boc-1,3-diamino-n-propane can be reacted in a suitable solvent (eg., THF or chloroform) to form an imine intermediate. The solvent may then be evaporated under reduced pressure, and the residue redissolved in DMF. The imine is then reacted with 7-nitro-homopthallic anhydride, (i.e., 7-Nitro-1H-2-benzopyran-1,3(4H)-dione) to produce a 7-nitro-3,4-dihydroisoquinolin-1(2H)-one, such as tert-butyl (3-(3-(4-cyanophenyl)-7-nitro-1-oxo-3,4-dihydroisoquinolin-2(1H)-yl)propyl)carbamate (Intermediate 1). The nitro group of the 7-nitro-3,4-dihydroisoquinolin-1(2H)-one can then be treated with a reducing agent, such as hydrogen in the presence of 10% palladium on carbon, in a suitable solvent (MeOH) to give a 7-amino-3,4-dihydroisoquinolin-1(2H)-one, such as tert-butyl (3-(7-amino-3-(4-cyanophenyl)-1-oxo-3,4-dihydroisoquinolin-2(1H)-yl)propyl)carbamate (Intermediate 13). The 7-amino-3,4-dihydroisoquinolin-1(2H)-one may be dissolved in a suitable solvent (eg., benzene) and then be treated with an organic isocyanates, such as 4-acetylphenyl isocyanates, in the presence of a strong base (eg, DIPEA) to produce a urea, such as tert-butyl {3-[7-({[(4-acetylphenyl)amino]carbonyl}amino)-3-(4-cyanophenyl)-1-oxo-3,4-dihydroisoquinolin-2(1H)-yl]propyl}carbamate (Intermediate 23), a compound which falls under the scope of the invention. At this stage, those skilled in the art will appreciate that many additional compounds that fall under the scope of the invention may be prepared by performing various common chemical reactions. For instance, a sulfide group may be oxidized to sulfoxide or sulfone groups by treatment with a suitable oxidizing agent (eg., m-chloroperbenzoic acid). Or, for example, the t-butylcarbamate group may be removed by treatment with a strong acid, such as trifluoroacetic acid, to give an amine product, such as 1-(4-acetyl phenyl)-3-[2-(2-aminoethyl)-3-(4-cyanophenyl)-1-oxo-1,2,3,4-tetrahydroisoquinolin-7-yl]urea (Compound 2). Details of certain specific chemical transformations are provided in the examples.

Those skilled in the art will be able to routinely modify and/or adapt the following scheme to synthesize any compounds of the invention covered by Formula I.

DETAILED DESCRIPTION OF THE INVENTION

It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention claimed. As used herein, the use of the singular includes the plural unless specifically stated otherwise.

It will be readily apparent to those skilled in the art that some of the compounds of the invention may contain one or more asymmetric centers, such that the compounds may exist in enantiomeric as well as in diastereomeric forms. Unless it is specifically noted otherwise, the scope of the present invention includes all enantiomers, diastereomers and racemic mixtures. Some of the compounds of the invention may form salts with pharmaceutically acceptable acids or bases, and such pharmaceutically acceptable salts of the compounds described herein are also within the scope of the invention.

The present invention includes all pharmaceutically acceptable isotopically enriched compounds. Any compound of the invention may contain one or more isotopic atoms enriched or different than the natural ratio such as deuterium ²H (or D) in place of protium ¹H (or H) or use of ¹³C enriched material in place of ¹²C and the like. Similar substitutions can be employed for N, O and S. The use of isotopes may assist in analytical as well as therapeutic aspects of the invention. For example, use of deuterium may increase the in vivo half-life by altering the metabolism (rate) of the compounds of the invention. These compounds can be prepared in accord with the preparations described by use of isotopically enriched reagents.

The following examples are for illustrative purposes only and are not intended, nor should they be construed as limiting the invention in any manner. Those skilled in the art will appreciate that variations and modifications of the following examples can be made without exceeding the spirit or scope of the invention.
